Since the ultra-high-power COB is a device with multiple LED chips, its application environment is mostly high-altitude scenes that are not easy to maintain. Once a certain link is neglected, the entire lamp will burn out. Therefore, the reliability and lifespan requirements of ultra-high-power COBs are much higher than those of general LED application scenarios. K-COB relies on the core material technology of the Chinese Academy of Sciences - transparent fluorescent ceramics, combined with a unique packaging design to form a patented low thermal resistance packaging technology, realizes a kilowatt-level high-power high-density COB light source module, has completely independent intellectual property rights, and breaks through international patent barriers. K-COB Lighting specializes in high power LED luminaires for industrial indoor and outdoor lighting. Contact us to find the perfect COB LED chip and lighting solution for you
